Yep, me too.  But I'm biased.

I could add my ksh.kshrc and ksh.cdhist is very cool "cd -l" list 
directories you've recently visited, cd -3 cd's to the 3rd last etc.
Only problem with ksh.cdhist is the original author is unknown, the 
colleague who gave it to be mentioned the author's name and that I could 
use/abuse it etc.  But I didn't note the guys name and now don't
remember - it was nearly 10 years ago ;-)

ksh.kshrc at least works with bash too - not sure about ksh.cdhist.
Both can be found at http://www.crufty.net/ftp/pub/unix/configs/etc/
if anyone is interested.
